On Some Foundational Issues Concerning the Relationship Between Risk and Resilience
(Peer reviewed; Journal article, 2021-10)“Risk” and “resilience” are both terms with a long history, but how they are related and should be related are strongly debated. This article discusses the appropriateness of a perspective advocated by an active “resilience ... -
On the activation energy for the formation of a critical size water cluster in structure I and structure II gas hydrates
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In the present thesis, experiments have been performed in order to study the activation energy for the formation of a stable, critical size water cluster in structure I and structure II gas hydrates. This activation energy ... -
On the algebraic classification of pseudo-Riemannian spaces
(Journal article; Peer reviewed, 2011-12)We consider arbitrary-dimensional pseudo-Riemannian spaces of signature (k, k + m). We introduce a boost-weight decomposition and define a number of algebraic properties (e.g. the Si- and N-properties) and present a ... -
On the analysis of hydrocarbon leaks in the Norwegian offshore industry
(Journal article; Peer reviewed, 2012)There have been several major offshore accidents in different offshore regions since 2005. In Norway there have been several very serious near-misses during the last ten years, several of which involving serious hydrocarbon ... -
On the Certificate Revocation Problem in the Maritime Sector
(Peer reviewed; Journal article, 2021)Maritime shipping is currently undergoing rapid digitalization, but with increasing exposure to cyber threats, there is a need to improve the security of the ship communication technology used during operations across ... -
On the circadian organization of nitrogen and sulphur metabolism in Neurospora crassa
(PhD Thesis UiS;157, Doctoral thesis, 2012-04)The purpose of this thesis was to study the circadian organization of the nitrogen and sulphur metabolism in the filamentous fungi Neurospora crassa. Neurospora is an important model organism used in genetics and circadian ... -
On the effects of asset lifetime extension for safety instrumented systems (SIS)
(Masteroppgave/UIS-TN-ISØP/2020;, Master thesis, 2020-07-15)A number of the offshore facilities in Norway have either been approaching their design life or exceeded them while there is still a considerable amount of oil and gas extractable in the field. Therefore, aging and life ... -
On the Fringe. Sheepdogs and Their Status Within Bronze Age Ontologies in Scandinavia
(Peer reviewed; Journal article, 2020)This contribution draws mainly on images of dogs, humans and sheep from Nordic Bronze Age rock art sources, but living arrangements within the household and depositional patterns of dog bones on settlements are also ... -
On the gap between theory and practice in defining and understanding risk
(Peer reviewed; Journal article, 2023-09)The risk concept is used in all types of situations and applications, ranging from technology to medicine and security issues. Many definitions of the concept exist, and there is an ongoing discussion on what is the most ... -
On the importance of systems thinking when using the ALARP principle for risk management
(Peer reviewed; Journal article, 2020-12)In this paper, we discuss the importance of systems thinking when using the As Low As Reasonably Practicable (ALARP) principle to support decision-making in risk management. The ALARP principle is a fundamental principle ... -
On the impossibility of deterrence in sequential Colonel Blotto games
(Journal article; Peer reviewed, 2012-06)A sequential Colonel Blotto and rent seeking game with fixed and variable resources is analyzed. With fixed resources, which is the assumption in Colonel Blotto games, we show for the common ratio form contest success ... -
On the meaning of and relationship between dragon-kings, black swans and related concepts
(Peer reviewed; Journal article, 2021-03)Different metaphors have been introduced to reflect the occurrence of rare and surprising types of events with extreme impacts, including black swans, grey swans and dragon-kings. Despite considerable research on clarifying ... -
On the numerical discretization of a tumor progression model driven by competing migration mechanisms
(Peer reviewed; Journal article, 2021)In this work we explore a recently proposed biphasic cell-fluid chemotaxis-Stokes model which is able to represent two competing cancer cell migration mechanisms reported from experimental studies. Both mechanisms depend ... -
On the optimization of actuator saturation limits for LTI systems: an LMI-based invariant ellipsoid approach
(Peer reviewed; Journal article, 2021)This paper considers the problem of optimal actuator dimensioning for LTI systems, in the sense of choosing appropriate saturation limits for a given set of admissible initial conditions and for a predefined integral ... -
On the Performance of Energy Criterion Method in Wi-Fi Transient Signal Detection
(Peer reviewed; Journal article, 2022-01)In the development of radiofrequency fingerprinting (RFF), one of the major challenges is to extract subtle and robust features from transmitted signals of wireless devices to be used in accurate identification of possible ... -
On the relationship between aquaculture and reduction fisheries
(Journal article; Peer reviewed, 2004-07)Recently, there has been a growing concern that increased aquaculture production poses an environmental threat to the species targeted in so-called reduction fisheries, the main source for fishmeal. The argument is that ... -
On the Same Wavelength: Surfers’ Perception of Wave Energy Technology
(Master thesis, 2024)In response to the escalating threat of human made climate change, mitigation measures are crucial. One of these measures is the departure from fossil fuels and the introduction of energy from renewable resources. As energy ... -
On the three-dimensional effects of the water entry of wedges
(Peer reviewed; Journal article, 2023-09)Three-dimensional (3D) effects on the total and spanwise slamming coefficients and the pressure reductions acting on the wedge surface during water entry are modeled in a unified manner. First, the water entry of wedges ... -
